There’s such a huge range of technical/musical ability in these “Greatest” bass-lines here. I know Hal Leonard is in the business to make money, and with the plethora of information freely available on the Internet nowadays; but seriously? Including a Green Day song as “the best bass-line ever?” And, a beginner-to-intermediate player is going to be able to pull off many of these tunes, while even some advanced players can’t quite pull off “YYZ.” Truly, the best way to learn songs is to advance to the level of learning by ear and transcription. This book (and those similar) won’t get anybody, anywhere.
